COMBINED HANDLE AND LOOK FOR CAR-DOORS.

Specification of Letters Patent.

Patented Nov. 25, 1913.

Application filed February 12, 1913. Serial No. 747,965.

To all whom it may concern Be it known that we, JAMES W. RUMsnY andWILLIAM H. SHnAsBY, citizens of the United States, and residents ofChicago, county of Cook, and State of Illinois, have invented certainnew and useful Improve,

rear edge of an edgewisely movable carcloor showing this inventionapplied thereto; Fig. 2 is a vertical section on the line 22 of Fig. 1;Fig. 3 is a horizontal section on the line 8-3 of Fig. 1; Fig. 4 is adetail perspective of the lock block or keeper; and Fig. 5 is a detailperspective view showing one way of making the lock block or keeperintegral with the wear-rail.

The object of this invention is to provide a simple device which willautomatically lock the door either in a fully closed or a fully openedposition, the locking device being adapted to be used as a handle orlever when in unlocked position for convenience in sliding the door backand forth, as more fully hereinafter set forth.

In the drawing a designates a part of a freight car siding and b anadjacent portion of the rear edge of a sliding freight car door. Set ina vertical slot cut in the door near its rear edge is a metal casing 0,this casing being rigidly fastened to the door by means of a series ofbolts (Z, these bolts being passed through the door body and through thebottom wall 6 of a depending trough-like extension f of the casing 0,this trough-like depending member being countersunk in the face of thedoor. The nuts 9 on the bolts OZ bear against the bottom wall 6 of thetrough and lie wholly within the trough. The casing c and itstrough-like extension are provided with a continuous integral marginalflange h which bears solidly against the front-face of the door.

The headed ends of the bolts (2 pass through the metal weather strip 2'fastened to the rear face of the door. On a horizon tal pivot jextending across the casing c is pivoted a locking lever whose upper endor nose 76 extends inwardly beyond the rear face of the door and isadapted to engage of the lower wall either one or two locking blocks ormembers Z fasten-ed to the car body. The handle part we of the locklever depends from the pivot, that is, lies approximately at rightangles to the lock nose is and is adapted when the door is locked ineither position, to lie within the trough member f, its inner faceabutting against the bottom wall 6 of the trough. Suitable recesses n inthis lever m are provided for the reception of the nuts 9, and a fingerpiece or extension 0 is provided at the lower end of the lever, thisfinger piece extending to a point below the lower end of the trough orchannel f for convenience in lifting the lever out of the trough or channel. A staple or perforated lug 79 projects forwardly from the bottom ofthe channel member f and extends through the registering opening in thelock lever m, the lever being provided with a pair of perforated ears 9,whereby the seal wire may be passed through the corresponding holes oropenings in the three lugs or cars, thus locking the lever m down in thetroughor channel. The lower outer corners of thekeeper blocks Z are eachbeveled off to form a cam surface 1 for the purpose hereinafter setforth, and fastened to the car body is a metal wear strip 8, this stripextending from a point near the left hand door post 25 to a point nearthe usual door stop a fastened to the car body. This strip is fastenedto the car body at a point just below the lock stops Z, and these stopsZ are fastened to the car body at points adjacent to the respective endsof this wear strip. In Fig. 5 I show the lock stops or members formedintegral with the wear strip, the end of the strip being bent orextended upwardly and forwardly upon itself to form a stop or block Z.'Any other sultable manner of forming these blocks integral with thewear strips may be employed, as is evident.

It will be observed that the handle end of the locking device is heavierthan the belt or nose end thereof and that therefore the tendency of thehandle is to fall by gravity; and it will also be observed that byreason of the location of the pivot j at the point shown this handlemember-normally rests against the bottom wall 0 of the channel f, whereit will be flush with the adjacent edges of the fixed member of thedevice, his member consisting of thecasing 0 and the channel memberdepending therefrom.

will unfailingly apprise the other persons who have an interest inknow-I ing the fact that the door is either open orf With this weightedhandle member it will be seen that the normal tendency of the lock boltor nose is is to swing upwardly, so that the device will automaticallylock the door either in a closed position or in its full open position.

The gravitation of the handle end of the locking member causes thelocking nose or bolt to swing up behind the keepers or look stops Z andthus lock the door in either a. closed or an open position. When the handle is raised to unlock the door it will be' seen that the proportionsof the parts are; such that by the time the lock nose is has been swungdown sufficiently to pass by the;v keeper Z it will lie in a plane infront of the wear plate 8, so that when the door is moved} in eitherdirection the lock nose will passin? I so that should the op-: eratorrelease the handle or bear down upon; it in the act of shoving the doorin eitherj nose will bear against? the strip 8 and slide therealong. This will; impmgmgf against the car body and thus scratching the, into thecar bodyg free movement of This cooperation of the wear plate and thelock nose will also prevent the handle dropping to locking positionuntil fully; closed, so that not only will the handle be} available as ahandle for sliding the door' front of this plate 8,

direction the lock prevent the lock bolt from pin therefrom or catchingand interfering with the the door.

the door is either fully opened or during the whole time that it ispartly open but it will be seen also that fully locked in one positionor the other.

A feature of importance lies in the fact. when the device is in lookingposition, handle entirely covers the; outer endsof the fastening boltsand the nuts thereon, so that it will be impossible for the look to bedisconnected from the car without first breaking the seal wire, which ispassed through the holes in the lugs 72 and that the gravitating and g.In this way unauthorized or burglar1ous opening of the door is renderedimpossible without breaking the car seal. The advantage in the beveledcorners r of the keepers Z is that these bevel faces cooperate with thelocking nose when the same is swung upwardly into locking position and;act as cams to asslst 1n forcing the door to a tight closure or to afull open position.

It will be observed that it is important that the parts shall be soproportioned that when the handle is raised to unlock the door thelocking nose shall by the time it has passed below the lower edge of thekeeper blocks Z be in position to engage with the front face of the wearstrip 8 when the door is moved slightly in the direction toward theadjacent end of the strip, whereby it will this provisiom attendant and;

be impossible to move the door from its locked position without at thesame time engaging the lock nose with the wear strip, whereby it will berendered absolutely certain that when the door is unlocked the handleshall be held in a raised position and whereby also it will beimpossible to slide the door in either direction without protecting thecar body against the impingement of the locking nose or bolt.

A further feature of advantage is that we so locate the stationarymember of the device that its fastening bolts cZ shall not only passthrough the car door body but also through the closure iron strip ifastened to the inner face of the door, whereby the locking device isfastened and anchored in a rigid manner. enabling it to withstand theroughest kind of service abuse.

Having thus described our invention, what we claim as new and desire tosecure by Letters Patent, is-
